Tanzania is a land of everything; Tanzanite, Kilimanjaro, Serengeti, Zanzibar etc.

Tanzanite is the blue/purple variety of the mineral zoisite (a calcium aluminium hydroxy silicate) discovered in the Mererani Hills of Manyara Region in Northern Tanzania in 1967, near the city of Arusha and Mount Kilimanjaro. Tanzanite is used as a gemstone, and naturally-formed tanzanite is extremely rare, still found only in the Mererani Hills.

Tanzanite is noted for its remarkably strong trichroism, appearing alternately sapphire blue, violet and burgundy depending on crystal orientation. Tanzanite can also appear differently when viewed under alternate lighting conditions. The blues appear more evident when subjected to fluorescent light and the violet hues can be seen readily when viewed under incandescent illumination. Tanzanite is usually a reddish brown in its rough state, requiring artificial heat treatment to bring out the blue violet of the stone.

The mineral was named by Tiffany & Co. after Tanzania, the country in which it was discovered. In 2002, the American Gem Trade Association chose Tanzanite as a December birthstone, the first change to their birthstone list since 1912.

The world's largest cut tanzanite recognized by Guinness World Records is 252.2 carats, and the largest rough tanzanite was a 16,839 carat (3.38 kg, or 7.46 lb) stone mined by TanzaniteOne in 2005.

Ryan Lochte's claims prompted a spoof poster to be displayed at the athletics stadium US swimmer Ryan Lochte has apologised for his behaviour in Rio and "for not being more careful and candid". The gold medallist had claimed that he and a group of fellow US swimmers had been robbed at a petrol station. But CCTV footage contradicted that story, showing the men had vandalised the petrol station after partying. Mr Lochte  tweeted : "I should have been much more responsible in how I handled myself and for that I am sorry." He said he had waited to issue the statement until it was clear that his teammates would be returning to the US. Rio's Mayor, Eduardo Paes, accepted the Americans' apologies: "I confess that my only emotion towards them is pity and contempt," he said. "It's a shame that they're such weak characters, that they have such personality flaws and it's up to the American Olympic Committee to sort it o...
